Name

svn upgrade — Upgrade the metadata storage format for a
working copy.

Synopsis

svn upgrade [PATH...]

Description

As new versions of Subversion are released, the format
used for the working copy metadata changes to accomodate
new features or fix bugs. Older versions of Subversion
would automatically upgrade working copies to the new
format the first time the working copy was used by the new
version of the software. Beginning with Subversion 1.7,
working copy upgrades must be explicitly performed at the
user's request. svn upgrade is the
subcommand used to trigger that upgrade process.

Notice that svn upgrade preserved
the local modifications present in the working copy at the
time of the upgrade, which were introduced by the version
of Subversion previously used to manipulate this working
copy.

Warning

As was the case with automatically upgraded working
copies in the past, explicitly upgraded working copies
will be unusable by older versions of Subversion,
too.
